i just finished doing the adjustment procedure and calibrated/tuned my jp4
it seems to be fairly solid except for one section
22. LFO VCF MODULATION
i have a newer model, i could not get the trimmer (26)to reduce the value to 100mv with the VCF MOD SLIDER set to 5. the lowest i could get it to was around 400mv
is there an easy way to check if that slider is faulty or does anyone have an idea where i should be troubleshooting?
